Hey Alex, thanks man! I've been neglecting this thread since September was so busy. I will say that I almost bought a VH45 and 300ZX trans the other day, but then I snapped back to reality. Also considered buying the used Stahl header in the classifieds. What's wrong with me... I really need to put my JCCS stuff up, stay tuned!

A V8, cross-flow engine is also not analogous to the L-series.

An air-cooled, long-runner VW engine is not analogous to a water-cooled L-series. If you're worried about stagnation in the thermostat housing, then don't turn the HVAC to full hot.

I would hope that if you're going skiing in the Z, you have your heater hooked up! With the heater on, hot coolant gets shunted from the back of the head to the water pump inlet thus performing a similar function to the manifold loop. Now, assuming that the heater is connected and functional may be a big IF for Z-car owners (including myself ). I think icing is the big issue at play here, so if the car is only driven in warm climates, removing it doesn't cause much issue. There will be no water pump cavitation if the HVAC control is switched to HEAT while the car is warming up. Warm-up time will be affected, but not too badly if the temperature is already "warm".

OSPHO or Naval Jelly should take care of it.

A can of engine enamel is a lot cheaper.

Fire kindling.

Pelican shows them as being the same PN: http://www.pelicanparts.com/catalog/shopcart/MISC/POR_MISC_mohubs_pg7.htm

Adjust valve lash and check cam timing while doing so. The FSM has all the info for this, download it from xenons130.com.

My '71 also had rivets.

Very nice! I'll have to get a quote when the time comes.

Looking good. Do you have the part number for the merge collector? I plan to go single eventually as well, I may have to take some elements of your design if you don't mind!

My Z's don't have EGR, so I don't know. However, you will automatically fail smog for no EGR on your ZX.

I'm not sure about the 280Z, but most modern EFI systems have a "flood clear" mode, i.e. if the TPS detects WOT at cranking the ECU will turn off the injectors.

Clive! You're not allowed to post porn on hybridZ!!!

As for the carb-manifold interference, how about some thicker soft mounts between the two? Like seen here: http://forums.hybridz.org/index.php/topic/109179-triple-40mm-mikunis-and-n42-head/page__pid__1021537#entry1021537 I know Dave (cygnusx1) made a bellcrank to use the cold start units with minimal hassle.

Yes, enjoy it! I try to work on the Z only when I'm satiated with driving it around and/or some issue is really bugging me.

"Finish" it up and drive it for a while. After logging a few thousand miles, you'll have a good list of stuff to do, believe me!

Bingo.

That's great! I'll be doing this eventually when I get back to work on my 240Z shell (whenever that will be ). Good write-up!

Nicely done! A bit less cumbersome than the 1st iteration. It will be nice to have cruise in the Z for those long highway trips.

Looking good! I'm digging the Clifford Research header. Let me know if you have any questions regarding Megajolt.

Sounds like a damper issue to me. You are having to soften the Tokicos, which have very stiff compression damping, a lot in order to be comfortable. However, given the "bounciness", this says that the spring rate/damper combo is now very underdamped, meaning that the damper has less control of the spring/mass. A damper with relatively stiff low-speed damping but softer high-speed damping should still perform well, while riding better. I'm hoping to find a damper that can accomplish this and accomodate a Z coilover install as well, as my Z has Eibachs/HPs now which ride rough and have very little bump travel before the ES poly bumpstop (which I haven't cut, yet). The nicer bump stops should help too, if you hit them often. Just take a look at a bumpstop some time and it will be pretty obvious whether you're been riding them or not. A lower unsprung/sprung weight ratio will improve ride and generally decreasing unsprung weight (wheels, tires, brakes, some suspension parts, etc.) will have a positive effect on ride, handling, acceleration, braking and traction.

You're right on the former bit, but not the latter. Higher velocity generates more "backpressure" (pumping losses).

I always have a pair in the car, can't go more than 30min without them.
